Spoon filling into pan. Bake for 55 to 65 minutes, or until center is set. Cool 15 minutes; loosen sides of cheesecake from pan with a knife. Leave to cool completely.

Stir together sour cream, sugar and vanilla. Spread evenly over top of cooled cheesecake. Spoon out 2 to 3 Tbsp. cherry sauce from pie filling; drop by teaspoonfuls onto topping. Pull a knife through cherry sauce to form hearts. Cover and refrigerate at least 4 hours. To serve, stir together remaining pie filling and orange juice in medium bowl; spoon over cheesecake.
